[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing a tread of a passenger conveyor used for removing a tread of a passenger conveyor.

[0002]

2. Description of the Related Art As a conventional passenger conveyor tread plate removing device, as described in Japanese Utility Model Laid-Open Publication No. 63-21687, an engaging hole is provided in a tread plate, one end of which is engaged with the engaging hole, and the other end thereof is engaged. There has been proposed a device in which a tread is removed by operating to rotate the tread.

[0003]

Problems to be Solved by the Invention Since the conventional stepping device for a passenger conveyor has been constructed as described above,
Although it is effective to lift the tread slightly before removing the tread, it is not appropriate to lift a tread of about 25 kg by one piece. It has to be provided, which affects the configuration of the treads of the passenger conveyor. Further, when inserting one end of the tread plate removing device into the engagement hole and rotating the other end,
In some cases, this rotating force could damage the tread.

An object of the present invention is to provide an apparatus for removing a tread of a passenger conveyer, which can easily remove the tread without processing the tread, and can easily lift and move.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, according to the present invention, a tread plate of a passenger conveyor for carrying a passenger is detached from a chain to which a driving force is transmitted, and the tread plate of the passenger conveyor is lifted and moved. , A U-shaped engaging portion that engages with the tread plate in pairs from the left and right sides thereof, an arm that connects the pair of engaging portions, and an engaging pair that is connected to the arm A handle for connecting the two arms together at a position deviated to either side of the portion, and a spring for applying a force in a direction in which the pair of engagement portions located on the left and right sides of the tread plate approach each other. It is characterized by having.

[0006]

According to the present invention, as described above, the stepping plate removing device for the passenger conveyor engages the stepping plate using the four engaging portions, and holds the stepping plate with a spring so that the engaging portions are not disengaged. As a result, the tread plate can be lifted without forming an engaging hole or the like, and both arms are positioned at a position deviated to one of the pair of engaging portions connected to the arm. Because comrades are connected by hand,
When the handle is lifted with the hand, the treadboard is in a balanced state so that the center of gravity is located directly below the handle, and the handle approaches the body, and in this state, lift it in a stable position and move it while lifting it Can be.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are a perspective view and a side view of an apparatus for removing a tread of a passenger conveyor according to an embodiment of the present invention.
Two pairs of engaging portions 3a, 3b and engaging portions 4a, 4
b is formed in a substantially U-shape to be engaged with a tread plate 5 described later, and a pair of engaging portions, that is, the engaging portions 3a and 3b are respectively connected to ends of the substantially U-shaped arm 3, The engagement portions 4a and 4b are respectively connected to ends of the substantially U-shaped arm 4. The arms 3 and 4 are rotatably fitted and connected to connecting portions 2 welded to both ends of the handle 1, respectively. The two connecting portions 2 connect the handle 1 and the arms 3 and 4 not at the center of the arms 3 and 4 but at offset positions. More specifically, one end of the handle 1 is connected to the arm 3 at a position deviated to either one of the paired engaging portions 3a and 3b provided on the arm 3, for example, the engaging portion 3a. In addition, the other end of the handle 1 and the arm 4 are provided at a position deviated to either one of the pair of engaging portions 4a and 4b provided on the arm 4, for example, to the engaging portion 4a.
Connecting between the two. Further, spring mounting members 3c and 4c are respectively attached to the intermediate portions of the arms 3 and 4 in the height direction, and the arms 3 and 4 are provided at intermediate positions in the width direction of the spring mounting members 3c and 4c, respectively. Springs 6 for applying forces in directions approaching each other are connected.

FIG. 3 is a perspective view showing a use state in which the tread is removed by the tread removing device of the passenger conveyor of the present invention. Now, when removing the tread plate 5 of the passenger conveyor, the deck cover and skirt guard (not shown) and the front wheel roller holding rail 11 are removed, and the tread plate 5 and the shaft 9 are not shown. Remove the bolt. A front wheel roller 8 running along a guide rail 7 is rotatably provided on the shaft 9, is connected to an endless chain 10, and runs as the chain 10 moves.

[0009] In this state, the above described stepping device for a passenger conveyor is used. First, the left and right arms 3, 4 are slightly widened from the horizontal width of the stepping plate 5, and the U-shaped engaging portions 3a, 3b and The engaging portions 4 a and 4 b are engaged with the left and right side surfaces of the tread plate 5. Then, the spring 6 moves the left and right arms 3,
4, so that the U-shaped engagement portions 3a, 3
b, 4a and 4b press the tread plate 5 from the left and right. Next, when the operator stands with the engaging portions 3a and 4a and lifts the handle 1 with both hands, the handle 1 is biased and attached. Lift and move without lifting and lifting. Further, since the posture of the middle waist during removal of the tread plate 5 and lifting movement is eliminated, no physical burden is applied.
Moreover, the engaging portions 3a, 3b, 4a, 4b provided at the ends of the left and right arms 3, 4 of the tread plate removing device of the passenger conveyor.
To engage the tread plate 5 from the left and right,
It is not necessary to process the tread 5 as in the prior art.

In the above embodiment, the tension spring interposed between the arms 3 and 4 is used as the spring 6 for preventing the left and right arms 3 and 4 from expanding. Even if a helical spring is interposed between the arm 2 and the arms 3 and 4, and the helical spring applies a rotational force about the connecting portion 2 to the arms 3 and 4, the same effect as in the above embodiment can be obtained. can get.

[0011]

As described above, the apparatus for removing a tread of a passenger conveyor according to the present invention engages a tread using four engagement portions and uses springs to prevent the engagement by these engagement portions from being released. Because it is held, it can be lifted without forming an engaging hole or the like in the tread plate, and a position deviated to one side of the pair of engaging portions connected to the arm. Because the two arms are connected with the handle with the handle, if you lift the handle with your hand, the tread will be in a balanced state so that the center of gravity is located directly below the handle, and the handle approaches the body, and in this state It can be lifted in a stable position and moved while lifting.
